With the continuous development of science and technology. Many scientific and electronic products are being manufactured. The experimental film blowing machine is also a kind of technical product. Its function is a mechanical product that melts particles and then blows them into a film. So what is the principle of the experimental film blowing machine?
(1) Production process and production principle: Dry polyethylene particles are added to the lower hopper. And the weight of the particles from the hopper enters the screw. When the pellets contact with the thread bevel. The rotating bevel faces the plastic to produce the bevel. The vertical thrust pushes the plastic particles forward. During the process, due to the friction between the plastic and the screw. The plastic and the barrel, and the friction between the particles. It also dissolves due to the external heating of the barrel. The molten plastic is filtered by the machine head to remove impurities from the die die mouth, cooled by the air ring, blown through the herringbone board, traction rollers, and rolled to roll the finished film into a cylinder.

(2) The main structure of the film blowing machine is composed of an extruder, a die head, a cooling device, a bubble stabilizing frame, a herringbone plate, a traction roller, and a winding device.
1. Extruder: The extruder is composed of screw, barrel hopper, deceleration and drive motor. The drive motor uses electromagnetic speed regulation motor (also can use ordinary frequency conversion motor). The reducer is driven by belt drive to make the screw in the barrel. Rotating motion; the plastic that melts the plastic particles of the hopper under external heating is extruded from the die mouth through three-pass filtration
2. Tee: It consists of three parts: filter screen, filter plate and tee gland.
3. Cooling device: composed of cooling air ring, air pipe, blower, etc.
4. Traction device: It consists of main components such as traction frame, herringbone, traction roller, winding mechanism and traction motor.
5. Electrical control part: Generally, the unit is equipped with a unit operation cabinet. The main button is used to switch on the main power and the motor main switch is turned on. The body and tees can be controlled by the separate button switch. The two sets of coils use thermocouple automatic temperature measurement and automatic temperature control. During normal production, the temperature can be controlled to ensure the production process is stable and reliable. There are many types of film blowing machines, including PE, POF and so on.
Today, to protect the environment, many items can be reused. Plastic items are recycled into plastic particles. We can use an experimental film blowing machine to test its film forming performance, which can save resources.
